About 2 months ago there was a major battle with the Worm spreading accross the internet world causing computers to reboot due to some RPC problems.It affected me as well, but I removed it safely and it was gone for good.Important thing to mention is that I run my internet connection with disabled firewall, as it causes a lot of problems to Squawbox connection for Vatsim online flying which I do very often.Now, yesterday the horror started again - RPC will reboot now.Just prior to this incident I reinstalled my video drivers, as they were causing me problems.I ran the worm fighting software once again (I still had it on my drive fortunately). it found the worm and removed it. I reboot the computer but the problem of RPC remained. I started experimenting and found that enabling my firewall solves the problem. It does not reboot on its own. Problem is it would not wotk with Squawbox. Is there any cure?Thanks for your help.Dom
